[Vespers War]

Not thoughts about the linked article, but one thing that's come up in discussions I've been having elsewhere is that Russia's active protection systems are turning out to be largely ineffective against modern anti-tank missiles because their maximum elevation means they can't engage a pop-up top-attack missile like Javelin or Spike. None of them - not Drozd, Drozd-2, Arena, Arena-M, or Afghanit - can elevate much beyond 20 degrees. Afghanit can only engage with smoke dischargers, and none of the others can do anything. This is where Trophy ends up having an advantage because it can elevate almost to vertical.

The Russian APS systems would still be useful against the older systems being sent like LAW or AT-4, but their ERA packages can also defeat those lighter warheads, even one as light as Kontakt-1. Since Russian defensive systems generally don't work well together (I think Afghanit/Malachit are the only APS and ERA that can be on the same vehicle at the same time), the older APS may be virtually worthless on heavy armored vehicles (e.g. tanks) these days. Anything they can protect against, ERA can also protect against for similar weight, less power draw, and generally better odds against the first strike (possibly worse against follow-up attacks depending on the attacker's accuracy).

IFVs with APS systems would be useful because IFV-mounted ERA tends to be very unfriendly to dismounted troops, and soldiers are trying to use the lighter rockets against them when possible, but other than the BMP-3M and Kurganets (neither of which are in serial production AFAIK), I don't think Russia has IFVs with APS.
